check conections on new parts just had that deal new cdi had one wire that pushed out just enough to lose contact. sounds strange but it happens.

replace the faulty fan relay or check for a problem wire from the ignition to the sensor to the relay

The startr motor is fried or u hav worn cables w alot of resistenc. Fixit bfor car fire

First make sure the carb.mounting flange is tight. being loose or cracked will allow air in leaning out the air fuel mixture. Next remove the low jet in the carb. its most likely plugged. try carb cleaner and blow it out with compressed air. Last resort,take the paper off of a twist tie and run it through the jet. If all else fails,buy a new one.thier only around 4 dollars.

It sounds like you have a bad starter motor.

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/dave_fb2c45146b845cea

Finger screw, (Idle Screw).. if the carb is CLEAN, new spark plug, valves properly adjusted, etc.. its only function is idle speed and it is what you are comfortable with!

Start at a turn and a half out.

You need to inspect all gas lines for obstructions including the gas tank , and especially the carb. I can bet dollars to doughnuts that it's a fuel problem something is blocking the fuel and by rocking it it's allowing the fuel to go through. hope this helps , let me know how you make out .

The spark plug is on the left side (shifter) of the head,,..?/ this is August.. if the atv has been sitting the carb may need a qualified professional to clean it again.. Replace the spark plug before you squirt anything in the engine...
